+ * This sample binder app has an extra consumer that is equipped with Pulsar's DLT feature - timeLoggerToDlt.
+ * However, this consumer is not part of the spring.cloud.function.definition.
+ * In order to enable this, add the function timeLoggerToDlt to the definition in the application.yml file.
+ * When doing this, in order to minimize verbose output and just to focus on the DLT feature, comment out the
+ * regular supplier below (timeSupplier) and then un-comment the ApplicationRunner below.
+ * The runner only sends a single message whereas the supplier sends a message every second.
